Industrial robots play a vital role in automation however only little effort are taken for the application of robots in machining work such as Grinding, Cutting, Milling, Drilling, Polishing etc. Robot parallel manipulators have high stiffness, rigidity and accuracy, which cannot be provided by conventional serial robot manipulators. The aim of this paper is to perform the modeling and the work...

Using workstation clusters (WSCs) is a practical and cost-e ective means of parallel computing. Fast workstations, using the latest RISC technology, can be assigned as computation nodes, however, communication between nodes is rather slow when using Ethernet. Recently, fast communication adaptors[2] have been developed, and the speed problem is being solved. We have developed a WSC called the R...

BACKGROUND Particulate matter (PM) exposure has been linked to increased risk of cardiovascular disease, possibly resulting from hypercoagulability and thrombosis. Lung and systemic inflammation resulting from PM inhalation may activate blood coagulation, but mechanisms for PM-related hypercoagulability are still largely unknown. OBJECTIVES To identify coagulation mechanisms activated by PM i...

The authors describe ACT-R/perceptual-motor (ACT-R/PM), an integrated theory of cognition, perception, and action that consists of the ACT-R production system and a set of perceptual-motor modules. Each module (including cognition) is essentially serial, but modules run in parallel with one another. ACT-R/PM can model simple dual tasks such as the psychological refractory period (PRP), includin...

rra/w-[Ru(S03H)2(N H ,)4], monoclinic, space group P2 Jn, Z =2, a 619.4(3), b = 701.8(3), c = 1068.6(6) pm, ß = 96.32(3)°. In the centrosymmetric octahedral complex the two inde­ pendent R u -N bonds are equal within experimental error (average R u -N 214.0 pm). The rather short R u -S bonds (227.6 pm) indicate a very weak rrarcs-influence o f the S 0 3H li­ gand. Caused by the protonation, one...

In this paper, the mobility and motion characteristics of a special 3-UPU parallel mechanism (PM) are studied. Using the screw theory and geometric method, the mobility of this PM is analyzed. When the moving platform and the base are not parallel, it has two rotational and one translational DOF. There is always a midperpendicular plane between the base and the moving platform. The moving platf...

So far, little is known about the neurocognitive mechanisms associated with emotion effects on prospective memory (PM) performance. Thus, this study aimed at disentangling possible mechanisms for the effects of emotional valence of PM cues on the distinct phases composing PM by investigating event-related potentials (ERPs). Participants were engaged in an ongoing N-back task while being require...

The two translational degrees-of-freedom (DOF) and one rotational DOF (2T1R) planar parallel mechanisms (PMs) have the characteristics of simple structures, kinematic dynamic models, ease control allow for a variety application prospects. This paper concentrates on derivations 5-DOF hybrid manipulators based synthesized mechanisms. To understand effect constraint motion rigid body clearly, meth...

This paper proposes a novel hybrid-type permanent magnet motor (HPMM) that simultaneously applies ferrite-PM (Fe-PM) to reduce the amount of NdFeB (Nd-PM) used in electric vehicle traction motors. Conventional HPMM can be divided into parallel type (P-HPMM) and series (S-HPMM). P-HPMM is advantageous for PM torque improvement because it obtain high flux linkage, but there problem Fe-PM demagnet...
